Hi Guys I bought a PT100 (RTD) Thermo sensor.It has 3 wires Red,Black & White.
The first probelm which I'm facing is to how i can test this PT100 in a bridge ciucuit.....???? Suggest me the resistance value which i use in the bridge along with pt100 and how i can connect 3 wire pt100 in a bridge circuit...... please help me and give our answer through circuit diagram and label the 3 wire of pt100 in your circuit so that i can understand better.
I'm not using any amplifier with the bridge. May use it or not ??? If YES then how.....I have 741 op-amp to work with..
What I need is I want to measure the temperature from 0'C to 500'C.
I need to scale this to 0-5V range so I can interface this with 8bit ADC and atmel 80S51 microcontroller and send these digital data to PC through serial port.
Waiting for your reply...!
